Monovision is a treatment often prescribed for people age 40 and older who are affected by presbyopia. Presbyopia occurs when, as part of the natural aging process, the eye's crystalline lens loses its ability to bring close objects into clear focus.
With the monovision treatment, you wear a contact lens for near vision on one eye and, if needed, a lens for distance vision on the other eye. Most people who try monovision are able to adjust to it.
For successful monovision treatment with contact lenses, talk to your optometrist about the pros and particularly the cons of this treatment.
Alternative treatments for presbyopia include a combination of contact lenses and reading glasses, or your doctor may prescribe bifocal contact lenses.
